Lycoming LTS101
The Lycoming LTP 101 (now Honeywell LTP 101 ) is a turboprop gas turbine for aircraft. The turbine largely corresponds to the helicopter turbine shaft Lycoming LTS 101 (now Honeywell LTS 101, Avco Lycoming LTS meantime also 101 or Textron LTS 101).
The compressor consists of an axial and a radial step. After the reverse -flow combustion chamber, the working gas is expanded in each of an axial turbine for the compressor drive and the drive shaft. The turbine can drive both train and compressive screws.
The FAA approval was granted in 1976. Standard, the turbine including in the Piaggio P.166 - DL3 and the Air Tractor AT -302 was used. For this purpose it was used for various conversions, so a upgraded Dornier Do 28 D Skyservant was shown in 1978 at the ILA in Hanover. Even with a trial version with turboprop engines of the Britten- Norman BN -2 Islander it was used. In addition there are a number of conversions of Cessna 360 and Cessna 421 by Riley Aircraft Corporation.
The LTS 101 is used among other things as a driver for the Bell 222, Eurocopter HH- 65A, MBB -Kawasaki / Eurocopter BK 117 Eurocopter and AS350D. Since its approval in 1975 more than 2000 units were built.
The latest stage is the LTS101 - 850B -2, which will provide 15 % more starting power and 18% more power in low-oxygen conditions ( hot & high). After their certification it is offered for the BK 117. This existing turbines already be retrofitted with new parts.
